  • Publication number: 20250076610
    Abstract: The present application provides an automatic focusing method for a fluorescence imaging device, including: S1, obtain a relationship function curve Z-Fv; S2, Gaussian fitting is performed on the relationship function curve Z-Fv, to obtain a standard Gaussian function f(x); S3, the object lens is arranged at three different travel coordinates, to obtain three groups of coordinate-clarity data (Z, Fv); S4, any two groups of the data are taken from the three groups of the coordinate-clarity data (Z, Fv) obtained in S3 and perform the Gaussian fitting with a standard deviation ?, to obtain a Gaussian function f1(x); and S5, an average value ?1 of the Gaussian function f1(x) is calculated, as a preferred travel coordinate Z? for this time of the focusing object lens. The present application solves problems of large focusing clarity error and slow focusing speed of the fluorescence imaging device in existing technologies.

  • Publication number: 20240070818
    Abstract: The present disclosure provides an image synchronizing method, a system and a piece of electronic equipment, which can invoke a preset frame synchronization parameter when receiving fluorescence image data; and white light image data corresponding to one memory chip is invoked from N memory chips based on the frame synchronization parameter, and the white light image data is fused with the fluorescence image data, so as to obtain a first fusion image. Under a case that the white light image and the fluorescence image generate difference, this method may compensate for the difference between the white light image and the fluorescence image in a manner that the white light image data after the difference is invoked through the frame synchronization parameter, thereby ensuring an imaging effect of a fluorescence imaging system.
